The dark side of data

What kind of data is your cell phone company collecting? Malte Spitz wasn’t too worried when he asked his operator in Germany to share information stored about him. Multiple unanswered requests and a lawsuit later, Spitz received 35,830 lines of code — a detailed, nearly minute-by-minute account of half a year of his life.

Recent events have highlighted, underlined and bolded the fact that the United States is performing blanket surveillance on any foreigner whose data passes through an American entity — whether they are suspected of wrongdoing or not. This means that, essentially, every international user of the internet is being watched, says Mikko Hypponen. An important rant, wrapped with a plea: to find alternative solutions to using American companies for the world's information needs.

Our leaders need to be held accountable, says journalist Heather Brooke. And she should know: Brooke uncovered the British Parliamentary financial expenses that led to a major political scandal in 2009. She urges us to ask our leaders questions through platforms like Freedom of Information requests — and to finally get some answers.

The line between public and private has blurred in the past decade, both online and in real life, and Alessandro Acquisti is here to explain what this means and why it matters.

Lorrie Faith Cranor studied thousands of real passwords to figure out the surprising, very common mistakes that users — and secured sites — make to compromise security. And how, you may ask, did she study thousands of real passwords without compromising the security of any users? That's a story in itself. It's secret data worth knowing, especially if your password is 123456 ...

We live in a world run by algorithms, computer programs that make decisions or solve problems for us. In this riveting, funny talk, Kevin Slavin shows how modern algorithms determine stock prices, espionage tactics, even the movies you watch. But, he asks: If we depend on complex algorithms to manage our daily decisions — when do we start to lose control?

Do you like curly fries? Have you Liked them on Facebook? Watch this talk to find out the surprising things Facebook (and others) can guess about you from your random Likes and Shares. Computer scientist Jennifer Golbeck explains how this came about, how some applications of the technology are not so cute — and why she thinks we should return the control of information to its rightful owners.

Todd Humphreys forecasts the near-future of geolocation when millimeter-accurate GPS "dots" will enable you to find pin-point locations, index-search your physical possessions ... or to track people without their knowledge. And the response to the sinister side of this technology may have unintended consequences of its own. (Filmed at TEDxAustin.)

The founder of 4chan, a controversial, uncensored online imageboard, describes its subculture, some of the Internet "memes" it has launched, and the incident in which its users managed a very public, precision hack of a mainstream media website. The talk raises questions about the power — and price — of anonymity.

Del Harvey heads up Twitter’s Trust and Safety Team, and she thinks all day about how to prevent worst-case scenarios — abuse, trolling, stalking — while giving voice to people around the globe. With deadpan humor, she offers a window into how she works to keep 240 million users safe.
